FRANK GUY, OF SPRINGFIELD, ILLINOIS.

VALVE.

Application filed January 5, 1916.

To all whom 'it `may conce/rn:

Be it known that I, FRANK GUY, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented a new and useful Valve, of which the following is a specification.

This invention relates primarily to valves for acetylene lamps, but is obviously applicable to other structures embodying a feed tube and a. valve. adjacent to the discharge end of the feed tube.

The purposes of my invention are: to provide a valve having a plurality of circumferential openings adapted to diffuse liquid radially, and means for accurately controlling simultaneous diffusion of liquid through all said circumferential openings; to provide,-in a valve,-in conjunction with a feed tube having a seat at one terminal of the tube, a valve stem, and a valve-plug in line with the tube; a rotatable member capable of grinding action on the tube and the plug and rotative independently of the valve stem and having a grinding surface complemental to the seat at the terminal of the tube and ar grinding surface complemental to the seating surface of the valveplug, to grind together the contacting surfaces of the rotatable member and the terminal seat of the tube, and the contacting surfaces of the rotatable member and the plug to remove any dirt or accretion betweenv them and fit them accurately to each other; to provide a rotative grinder adapted for accurate centering with respect to the feed tube and the valve plug; to provide means to prevent longitudinal or lateral displacement of the grinder and to provide other new and useful features of construction.

The invention is illustrated iu the annexed drawing, to which reference is hereby made, and will be hereinafter particularly described and finally recited in the claims.

Figure l is a diagrammatic longitudinal section of 'an acetylene lamp embodying the invention, and shows the valve and appurtenances in elevation. Fig. 2 is Aan enlarged partial longitiuilinal motion on the line X. X. of Fig. 1, and Figs. 3 and 4 are enlarged sectional diagrams illustrating details of modified forms of the valve.

. Similar reference numerals designate like `parts in the different. -iewsl I will first describe the preferred construction illustrated in Figs. l and 2 and will Specification of Letters Patent.

Patented sept. ie, 191e.

serial No. 70,550.

afterward describe the modified forms shown in the other views.

The lamp body which may be of any suitable material and of any suitable form, preferably comprises a carbid box l and a reservoir 2, detachably connected with each other preferably by a screw connection 3. The feed-tube si is fixed in the reservoir and extends through the reservoir bottom. and downward into the mass of carbid 6 in the box 1. An opening 7 in the wall of the tube l admits liquid from the reservoir into the tube. Adjacent to the upper terminal of the tube is an internally screw threaded part 8 in which Vthe screw '9 engages. The valve stem 10 is co-axial with and extends downwardly through the tube 4. The screw 9 is unitary with the stem l0. A handle lf2 in fixed relation to the screw 9, serves to rotate the screw to cause longitudinal movement of the stem 9. The

handle l2 is preferably a continuation of the valve stem 10, bent as shown; but the handle may be made separately and may be rigidly connected with the screw With-" out departure from my invention` f The tube -thas a fiared part 13 and a fiat terminal 29. The circular plug 14 is fixed on the stem 10 and has a tapered part 15 and a flat circular ledge 27. The bulb-like rotatable member 1G has a central bore 17 of substantially the same caliber' as the bore of the tube 4f to permit unobstructed flow of liquid within the tube and within the rotatable member and alsodias a tapered part 18 conformed to the flared. part 1,3 of the tube a, av circumferential ledge 30 adapted to grind and seat on the flat terminal '129 of the tube 4, a flared part 19 conformed to the tapered member 15 of the plug' l-.land a fiat terminal 28 adapted to seat and grind on the ledge 27 of the plug 14. The inclined surface of the part l5 of the plug engages on the inclined surface of the rotatable member to bring it into linegvith the tube and the plug and prevent lateral displacement of the plug` or the rotatable member. When the parts are assembled and the valve is slightly opened liquid from the. tube will be diffused radially through the space between the ledge 27 of the plug and the iatterminal of the rotatable member and between the ledge 30 vof the rotatable member and the flat terminal 29 of the tube 4.

The periphery4 of thedrotatable member isA cause slight downward movement of the plug, and thereupon the rotatable member may be pressed downward agamst the plug and may be rotated by hand to grind the member 28 on the member 27 to crush andremove the accretion, and if the rotatable member be then raised slightly, water from the tube will flow between the membersil), l5, 2?' and 2S and will thoroughly cleanse them. lf the valve becomes clogged by dirt or ash accumulating on the terminal 29 or on the part 30, the valve may be slightly opened and the rotatable member may be".

pushed upward against the seat 29 and may he rotated by hand to crush and remove the accretiou and to accurately grind the parts .9 and on eachother.-

lt is found in practice that when the parts are accurately fitted and assembled 'as described, slight opening of the valve will cause radial diffusion ot" liquid through the circumferential opening between the parts 29 and 30 as indicated by arrows Y and simultaneous radial diffusion ot liquid through the circumferential opening be tween the parts 27 and 28, as indicated by arrows Z.

A valve havingv a i, urality of circumferential openings adapet 'for radial diffusion nt liquid as described is of special value in acetylene lamps ol' thc type in. which the lower Wart of the valve is iuunersed in the mass ol' carbid and the water einer, ng From the valve is subject to the absorbent action ol the carbid, as shown in Fig. l, in that 'the plurality of accurately adjustable circumferentialopenings causes more uniform radial diffusion of liquid throughout the mass of carbid than has hitherto' been atlie.

tained, resulting in more unit'oimgencration of gas; and the' means for accurate con trol of the simultaneous discharge of liquid through all the openings facilitates convenient and complete control ofi the generation ot to suit all the dill'ecnt conditions of P3 illustrates a modified construction in' fig.

in which the terminal 2l otl the tube 4 is minal 23 of the tubel l and has a convex part 25 adapted to engage on the wall 32 of a complemental concavity 26 in the plug 14. In all the different forms the rotatable member is adapted to be rotated between the plug and the terminal ofthe tube and means are provided to prevent lateral displacement of the plug relative to them.

To distinguish that part ot' the tube 4 with which the grinder lG contacts, l call it the terminal of the tube. It is obvious "that, without departure from my invention, said terminal of thetube may be flared and flattened as shown in Fig. 2, or rtlat as shown in Fig. 3, or tapered as shown in Fig. 4, or maybe of other and different forms which will readily occur to persons skilled in the art; it is also obvious that the closure 1l may be of various and dilierent forms; and the rotatable grinder member 1G may be of correspondingly various and dill'erent -forms. lt is essential only that the terminal of the tube shall have a continuous or unbroken surface; that the closure shall have a continuous or unbroken surface, and that the rotatable grinder member shall havel a continuous and unbroken periphery, a continuous and unbroken surface complemental to and adapted to grind on the terminal of the tube and a continuous and unbroken surface coniplelnental to and adapted to grind on the closure.

Other analogous or equivalent 111odilications will readily occur to persons skilled in the art and need not be detailed here. It is essential only thatvthe rotatable member shall be rotative between the plug or closure and the terminal of the tube and shall be sateguarded against lateral displacement relativ.x to them. I wish to avail myself otl ali fair equivalents.

Having fully described my invention, what l claim as new and desire tosecure by Letters Patent is:
